Cost to Detached Garage Construction in Tucson, AZ (2026)
If you’re budgeting a detached garage construction in Tucson, most projects run $18,095-$54,285, 10% below the $35,000 national average. What moves that number most is usually one thing: Size and Number of Bays. On its own it can swing the cost by $10,000 - $40,000, so that’s the decision to slow down on before you sweat the smaller stuff.
Easiest place to save: Get engineering plans done once and use competitive bidding to get the best framing price. Having your own plans lets you get apples-to-apples bids from multiple framing contractors.
Why it costs this here: A carpenter in Tucson earns $25.95 an hour, 18% less than the $31.55 national average, 36th highest of the 49 metros we price. Labor is 42% of what this particular job costs, which is why Tucson lands where it does: the materials cost roughly what they cost anywhere, and the wage is what moves.
Scale of the spend: Against Tucson's median home value of $286,900 (Census ACS 2023), a typical detached garage construction here runs about 13% of the house's worth - a large enough share that it belongs in a resale-value conversation, not just a contractor bid.
The contractor market: The contractor market here is comparatively thin - about 1,291 specialty-trade businesses metro-wide (Census CBP 2022) - so book earlier than you would in a bigger metro and expect quotes to spread wider.
